You can't sign away statutory rights, they will be struck out of a document if someone tries to get to you do so (for consumers, not companies, B2B)
Mid term increases are a normal part of contracts. They always have been, less so in the consumer space since typically the contracts are short duration, but longer duration contracts in business are far more normal.
Long term leases, 5 year deals on equipment etc.
I would say you would have a high chance of getting a non refundable deposit on a contract where they can amend the price later deemed to be unfair and hence I would expect the resolution would be to make the deposit refundable.
Deposits do not typically guarantee anything, they are just a mechanism for companies to protect themselves from bad actors. Eg walking into a car dealer and ordering a car with a silly combo of items that you never intend to go with.
Mid contract rises are highly unlikely to be deemed unreasonable when they are linked to a commonly used mechanism, such as inflation.
Its always the same unfortunately. People ask for protection and then complain when it goes against them, even if they have benefitted previously.
Wasn't long ago people were complaining companies could put up your bill without any check. So they brought in a check, we will link it to X and allow a small adjustment as well.
No one cared when inflation was 1%, they suddenly care when its 12%.
